SMART monitoring for windows powershell script
Assuming you have SMART enabled on your windows disks, here's a powershell script that the Zabbix windows agent can use with template_smartd. While smart isn't a very good predictor of drive failure, it can alert you to heat issues. In this example, you'd call the script c:\drivetemp.ps1
Code:
#IT'S not my fault if you nuke your corp's domain controller hard disks....
#In a nutshell, this is a powershell v.1 script that calls smartctl.exe, does stuff with the values
#and echoes the data back to Zabbix.
#Define the parameters for Zabbix to call
param($arg1,$arg2)
#YOU MUST EDIT & TEST THIS for YOUR SYSTEM.
#start by executing smartctl.exe -a hda > disk1.txt on your system
#then open disk1.txt and start counting lines.
#zabbix_agentd.conf line for this in windows:
#UserParameter=system.smartd[*],C:\windows\system32\WindowsPowerShell\v1.0\powershell.exe c:\disktemp.ps1 $1 $2
# below is because I'm too lazy to change the parameter names I stole from here:
# http://www.zabbix.com/wiki/howto/monitor/os/linux/smart
#/dev/sda = hda in Windows
if ($arg1-eq "/dev/sda") {$arg1 = "hda"}
# WTF powershell comparison operator for equals is actually "-eq", but assignment equals is "=".
# Sorry, I did vbscript for a long time and would prefer to spend my syntax time learning
# python, because that's what all the cool kids write in these days.
if ($arg1-eq "/dev/sdb") {$arg1 = "hdb"}
#requires smartmontools (windows) at the location of your choice as long as it's right on the next line
# Execute smartctl and assign the output to a variable
$smartctl ="c:\smartctl.exe -A " + $arg1
# the numbers between the [] are the lines on smartctl -A output that you want
#each drive is different and windows doesn't have that many command-line tools to get everything you want
#so you're left to edit a script below
$smartdata = (Invoke-Expression $smartctl)[6..23]
$i = 1
do {
# all the below is necessary to replace one line of string manipulation in Linux.
$length = $smartdata[$i].ToString().length
$e = $smartdata[$i].ToString().Substring(4,24).Trim()
$d = $smartdata[$i].ToString().Substring(87,($length-87)).Trim()
# Temperature needs cleaning
if ($e-eq "Temperature_Celsius") {$d = $smartdata[$i].ToString().Substring(87,2) }
if ($e-eq $arg2) { echo $d }
$i=$i+1
#echo $i #useful for figuring out how many attributes you can get when you're debugging.
}
# while number needs equal the number of your data lines. You may need to change 15 to something else.
while ($i-le 15)
